If you have any question about how cruel people can be, you need look no further than the heartbreaking case of Amanda Todd. Last week the 15-year-old committed suicide after being relentlessly attacked by bullies. Sadly, even her extreme attempt to put a final end to the bullying hasn't stopped the malicious, vile behavior as bullies continue to target her memorial pages with their evil comments.

It's almost impossible to believe that anyone could be that heartless, but proof is right there on online memorial pages set up in her honor. While most of the comments are positive and uplifting, the ugly ones are beyond horrific. CTV reports that one came from a female, who identified herself as one of Todd's classmates: "I'm so happy she's dead now."

According to The Star, another shows an image of a female body hanging dead with a caption that reads: "Todding". Others said she deserved whatever she got as in seventh grade someone posted a topless picture of her, which was also posted on the sites. The National Post reports that someone else wrote, "I hope they sell Clorox in Hell," referring to a suicide attempt Todd had made in the past using bleach.

Anyone who thinks bullying is just kids being kids may want to rethink that after reading these comments. How does anyone sleep at night after doing something like that?

It's not known if those posting such horrific things on her memorial pages are the same ones that bullied her during her life. Either way it's disturbing -- either there are more sick, twisted people out there, or her tormentors simply have no conscience, no soul. Sadly, it's probably both.

This is a girl who had been bullied so maliciously during her short life that five weeks before her death she took to YouTube and posted a video titled, "My story: Struggling, bullying, suicide, self harm," expressing the agony she'd been through since someone leaked that photo of her in which she'd made a mistake. The brutal attacks and severe effects on her life since that time were overwhelming, but she seemed to be overcoming them.

In the end it seems she couldn't, and seeing how relentless the bullying is even in the wake of her death, perhaps gives us an even greater glimpse of the extreme level of hate she was up against.

We are looking at what transpired in regards to Amanda, what transpired on social media, what transpired face to face, who may have had contact with her in that regard, and whether there’s evidence to support any sort of criminal charge to any person or persons who may have had an impact in the type of decision Amanda made.

I hope they track down any and all of these malicious individuals and both expose them publicly and make them pay for their actions so that others might not suffer a similar fate. R.I.P., Amanda.

Can you believe anyone could be so heartless? What do you think drives people to act like this?
